Connect to your AI
I will turn your API into an mcp server for claude and chatgpt
Kaique Santos
About this gig
You have an API, a database or internal tools. Your team wants Claude and ChatGPT to use them. I will build the MCP server that connects the two.
You get:
- An MCP server in Python or TypeScript that turns your API into tools Claude, ChatGPT and Cursor can call
- Safe defaults: read only unless you choose which actions can write
- Tests for every tool, run against your real API before delivery
- A setup guide for Claude Desktop, Claude Code, ChatGPT and Cursor
- Optional remote hosting so your whole team can use it
Why me: I am a software engineer with 7+ years building backends on AWS, and I build and use my own MCP servers every day.
How it works:
- Send your API docs or database schema and the tasks you want AI to do
- I propose the tool list and you approve it
- You get the server, the test results and the setup guide
Not sure how many tools you need? Message me your API docs and I will suggest a tool list before you order.

FAQ
Which AI apps can use the server?
Claude Desktop, Claude Code, Cursor and other MCP apps. ChatGPT only connects to servers hosted online, so for ChatGPT choose Standard or Premium, or add the Cloud deploy extra to Basic.
Do I pay for the AI separately?
The server has no AI fees of its own. Your team keeps using its own Claude, ChatGPT or Cursor plan, and the server simply gives the AI access to your tools.
Is it safe to give an AI access to my API?
Tools are read only by default, and write actions are added only where you approve them. Your keys stay in environment variables, never in the code. Premium also logs every call the AI makes.
What do you need from me?
Your API docs (an OpenAPI file is ideal) or database schema, a test account or sandbox key, and the 3 to 5 tasks you want the AI to handle.
Where does the server run?
Basic runs on your own computer. Standard and Premium run in your own cloud account, such as AWS, Google Cloud, Fly or Railway, behind HTTPS with login. Hosting is billed to you directly.
What counts as one tool?
One action the AI can take, like "search orders" or "create a refund". Most tools use one or two endpoints of your API. I send the tool list for your approval before I start.
What if my API changes later?
You get the full source code and tests, so any developer can update it. I can also add new tools later with the Additional tool extra.
